I'm someone who's fairly sensitive to PWM. Have tried and returned iPhones, Pixels, and similar. Steam's OLED doesn't bother me. I think it's the same screen as the Switch OLED which also doesn't bother me. Wish Apple and Google would buy from that supplier.
But in general you're correct. When given a choice, I'll generally buy IPS when I can.
> Wish Apple and Google would buy from that supplier.
Apple and Google could do something about it if they wanted, even without changing supplier. They clearly don't think it's worth it. That's not surprising coming from Google but I admit I am surprised that Apple has no driver option to reduce flicker.
Most Chinese phone makers nowadays offer settings to reduce OLED flicker greatly, usually at the cost of color accuracy and/or a locked framerate.
